(BLOOMINGTON) - Authorities say a 73-year-old Bloomington man apparently drowned after crashing his vehicle into a small Brown County lake.

The body of John Grunwald was pulled from the water Monday near the former Ski World property.

Officials are now saying Grunwald suffered a massive heart attack shortly before the accident that, the Brown County Coroner says, would have killed him regardless of where his vehicle went afterwards.

Grunwald was found dead when DNR crews pulled his vehicle out of the water.
